We proposed a method for patient selection and application of criteria for predicting success with bone-conduction external acoustic stimulation using high-audio-frequency sound in the ranges of 10-20 kHz and 20-26 kHz for individuals with subjective idiopathic tinnitus (SIT) of the severe disabling type. Ultra-high-frequency (UHF) stimulation for tinnitus relief has been found to be most effective when residual neuronal function exists in the acoustic ranges of 10-14 kHz, with thresholds no greater than 40-50 dB sound pressure level (SPL). Ultrasonic (US) acoustic stimulation is recommended for patients with audiometric thresholds greater than 50-60 dB SPL for frequencies of 10-14 kHz. Fifty-two consecutive patients seen for the primary complaint of SIT of the severe disabling type received a trial of either UHF or US bone-conduction acoustic stimulation. Tinnitus relief was reported in 22 of the 52 patients. The application of criteria for patient selection predicted tinnitus relief in 20 of the 22.
我们提出了一种针对重度致残型主观性特发性耳鸣（SIT）患者的选择方法，并应用了相关标准，通过使用10 - 20kHz和20 - 26kHz范围内的高频声音进行骨传导外部声刺激来预测成功的可能性。已发现，对于耳鸣缓解的超高频（UHF）刺激，当在10 - 14kHz声学范围内存在残余神经元功能且阈值不高于40 - 50dB声压级（SPL）时最为有效。对于10 - 14kHz频率的听力阈值大于50 - 60dB SPL的患者，建议采用超声（US）声刺激。52例因重度致残型SIT为主诉前来就诊的连续患者接受了UHF或US骨传导声刺激试验。52例患者中有22例报告耳鸣缓解。患者选择标准的应用在22例中有20例预测了耳鸣缓解。
